Andrew Burgess a2c8f78df5 gdb: allow selecting default fg/bg colors in tui mode ...

This commit fixes PR gdb/32797, and pulls in just part of commit:

  commit 6447969d0a
  Date:   Sat Oct 5 22:27:44 2024 +0300

    Add an option with a color type.

to the gdb-16-branch.

This commit allows the escape sequences \x1b[39m and \x1b[49m, which
select the default foreground and background colours respectively, to
work correctly.

This fix is just a small part of the above commit.  Only these two
changes are required to fix this bug.  As we are currently preparing
for a 16.3 release, I don't think we should be pulling in the whole of
the above commit.

You can test this commit using:

  export TERM=xterm-256color
  gdb -q -tui -ex 'py print("normal\n\x1b[39mforeground default\n\x1b[0mnormal\n\x1b[49mbackground default\n\x1b[0mnormal\n")'

All of the output text should use the default foreground and
background colors.
